Prevalue Source Types Overview

There are some default prevalue source types that can be used. In this article, we will give a quick overview of them:

Get values from textfile

Upload a textfile that contains the prevalues. Each prevalue should have its own line in the file. Once the file has been uploaded, you can find it in ~/wwwroot/App_Data/UmbracoForms/Data/PreValueTextFiles/{GUID} where the {GUID}is replaced with the pre-value ID.

Umbraco Documents

Allows you to use content nodes from a specific source as prevalues. Configure the following options in the Details section:

• Define the root node by either:

  • Selecting the type of item the picker should target such as Content, Media, or Members, or

  • Specifying a dynamic root.

• Enable Use current page as root instead of choosing a specific root node. Preview is not available when this setting is enabled.

• Choose a specific Document type, if the selected root node contains a different Document Type.

• Select the Value field to define the value stored for the prevalue.

• Select the Caption field to define the label shown in the list.

• Enable List all Descendants of the selected root node to include all child nodes beneath the root.

• Select Order by from the drop-down list to display how the prevalue list is sorted.

• Select your preferred Cache option for caching the list of prevalues when rendering in a form.

SQL Database

Connect to a OleDB compatible database table and construct a prevalue source from it. Once selected, it will be editable from the Forms interface.

Configure the following options in the Details section:

• Connection string (either choose one from your web.config or add another from a textfield).

• Connection String from configuration

• Table Name

• Key Column

• Value Column

• Caption Column

• Select your preferred Cache option for caching the list of prevalues when rendering in a form.

Umbraco Data Type Prevalues

Choose an Umbraco Data Type to use its configured prevalue collection.

In the example below, the prevalue collection from a Data Type called Home - Font - Radio button is used:
